2.1.17 Installation of efficient windows (solar control double glazing with PVC frames)

Description

This measure consists in the replacement of inefficient windows (e.g. aluminium frame without thermal brake and single glazing) for an efficient one with solar control double glazing and PVC frames. Solar control glasses have the property of reflecting part of the energy of the received solar radiation, decreasing the amount of energy that passes through the glass. A typical transmittance of this type of windows is U=1.3 W/m2K.

Benefits

  • Reduce heat losses and air infiltration

  • Easy and fast installation

  • Improve comfort conditions

  • There is a wide range of colors, although white is the most widely used color, there are imitation wood, without a too high price

  • Solar control glasses cut utility costs by 30% to 40%

  • Solar control glasses can block 99% of UV light that fades furniture

Limitations

  • Double glazing cannot be repaired

  • During the summer months, trapping heat inside glass panes can lead to a stale and uncomfortable room

  • PVC frame is more expensive than the rest

  • PVC with high temperatures can be deformed

  • Valuable solar heat gain in colder climates can be reduced

Economic assessment

Energy costs are reduced.
